Yep, I've been working in a windowless cubicle for 31 years now.Window is where my airbrush spray booth will vent. They slide up or also will angle outwards. It's on the North side so I get light all day but its North light and not as bright as East/West. Better than nothing.
I worked 12 years in an office with no windows. Was kinda funny after a while. I would be in there from 8 AM until 6 PM. You would have no idea what was going on outside.
